Most parts of the Platinum Armor is made of an unbelievably strong, silvery-grey metal called platinum. These chests however have a greater chance of both containing Platinum Armor, though. Only found in the PVP Arena, the Platinum Armor/Sword set only appears in the short seconds after the battle (This period of time can only be accessed to the victorious team, as the losing team or both teams of a tied game will be sent straight back to the PVP Arena Lobby straight after the main part of the battle.)in two chests within the boundaries formed by three quartz white-colored pillars in the center of the arena. Platinum Armor is the eight and final tier of armor in the extended Windows version BrowserQuest created by Peter Sandberg Brun, and will unlock the 'A Rare Metal' achievement exclusive to BrowserQuest Extended once obtained alongside the Platinum Sword.
